AIR WASHER Filed May 28, 1935 3 sheets-sheet s 7 I Q m Invenlor PatentedFeb. 11, 1936 UNITED STATES PATENT OFFICE AIR WASHER Application May 28,1935, Serial No. 23,920

1 Claim.

This invention appertains to new and useful improvements in air washersadapted for use in conjunction with internal combustion engines, thesame being an improvement on our co-pending application Serial No.740,345, filed August 17, 1934.

The principal object of the present invention is to provide an airwasher employing a moistening medium to promote eradication of foreignmatter before delivery to the engine with which it is being employed.

During the course of the following specification, other importantobjects and advantages of the invention will become apparent to thereader.

In the drawings:

Figure 1 represents a side elevational view of the air washer showninstalled with an engine.

Figure 2 is a fragmentary top plan view of the washer.

Figure 3 is a fragmentary longitudinal sectional view through themanifold of the washer.

Figure 4 is a vertical sectional view taken substantially on line 44 ofFigure 2.

Figure 5 is a fragmentary horizontal sectional view taken substantiallyon line 55 of Figure 4.

Figure 6 is a cross sectional view taken substantially on line 6-6 ofFigure 2.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 generally refers to a Diesel type of enginewith air intake ports 6. The present invention employs an elongatedmanifold pipe 1 from which the spout 8 extends to engage into the airinlet port 6 of the engine, each spout B being provided with anupstanding lip 9 to limit the engagement of the spout into the port.

The washer consists of a rectangular (or any other decided shape) shapedcasing ID, the interior of which is divided by a transverse partition llmerging as at l2 with a horizontal partition l3, these partitionsdefining a chamber M with which and through the wall of the casing themanifold pipe I communicates.

Depending into the casing I!) through the top thereof is the stack I5terminating at its lower end in spaced relation to the bottom of theeasing and extending for a substantial distance at its upper end abovethe top of the casing. Extending into the stack l5 through the upperexternal portion thereof is the water conduit l6 which makes connectionas at H in the stack with the depending tube l8 terminating in a spraynozzle I9 located a substantial distance upwardly from the lower end ofthe stack.

A large bulbular mesh enclosure 20 is mounted at the upper end of thestack [5 and through this air must be drawn. Numeral 2| represents adrain pipe for the lower portion of the casing l0.

It can now be seen that when the motor 5 is in operation, air is suckedthrough the mesh 20 which removes all large foreign particles and asthis air is drawn downwardly through the stack IE it is treated by thespray from the nozzle l9.

This dampening or moistening of the air will obviously cause aprecipitation of all residual foreign matter to the bottom of the casingwhere it can be drained ofi through the pipe 2|. The remaining airpasses upwardly in a direction following the arrows in Figure 4 and outinto the manifold pipe I from where it is taken by the engine 5.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, size,and materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An air washer for engine comprising a casing, a transverse verticalpartition disposed substantially intermediately across interior of theeasing, a horizontal partition in the casing with which the verticalpartition merges to define a chamber, said vertical partitionterminating adjacent to the top of the casing, a discharge pipecommunicating with the interior of the casing at the chamber, a narrowinlet tube depending into the casing from the top thereof, said tubebeing provided with an air filter at the top thereof, the upper portionof the tube projecting above the top of the casing, a fluid conduitextending into the tube at the portion above the top of the casing, anda downwardly disposed nozzle at the inner end of the conduit.
